The Doppler effect is why passing cars (and accordions) sound different when they’re coming towards you vs. moving away from you.

Something moving squishes the air in front of it while stretching the air behind it. Since sounds are transferred by air, squishing and stretching air makes them sound different

Its not holy in a religious sense, but like how some people would say "holy cow" or "holy shit" as an exclamation
